This web application classifies received text messages using the Cohere Classify service and .NET. It uses Twilio for WhatsApp messaging and allows users to classify messages into predefined categories. The application receives a text message, processes it through the Cohere API, and returns the prediction with confidence level via a message to the user. To test the application, you need to set up the Twilio Sandbox for WhatsApp, make your webhook public using ngrok, and send a test message through WhatsApp. The application can be further optimized by adding more examples to improve the accuracy of predictions.
